[R-390] re: tube extenders

[wli]

Perry:

Tube extenders are useful. Look in those myriad of
unmarked boxes at hamfests. I found mine there for $2
apiece last year. You have to be on the lookout as
they do not turn up often....

One caveat: some of them may have a busted wire
INSIDE. Pays to check continuity between the pin and
the test point as well as the socket hole. I had two
such *defective* extenders, easily fixed with a short
piece of bare wire and a little surgery on the device.

I understand that many of us never use them, they are
better at diagnosis than I;.... and I need all the
help I can get.......
